60255 Stunt Team and 60256 Racing Cars are both motorsports themed, complementing one another. 60256 Racing Cars will scratch an itch for anyone disappointed about the LEGO Speed Champions format switching from six stud wide cars to eight stud wide cars.
60257 Service Station is a more traditional vehicle based set, offering a petrol station along with a car and camper van.
60258 Tuning Workshop includes a garage, hot rod, pick up truck, two cars and a motorcycle. A caravan that serves as the headquarters of a dodgy used car lot is also included. While back in the days of Town there were sets featuring this sort of subject matter, it is new for the LEGO City theme.
